DATASHEET
ISL83387E
+/-15kV ESD Protected, +3V to +5.5V, 1Microamp, 250kbps, RS-232 Transceivers
with Enhanced Automatic Powerdown and a Separate Logic Supply
The Intersil ISL83387E is a 3.0V to 5.5V powered RS-232
transceiver which meets ElA/TIA-232 and V.28/V.24
specifications, even at V
CC
= 3.0V. Additionally, it provides
15kV ESD protection (IEC61000-4-2 Air Gap and Human
Body Model) on transmitter outputs and receiver inputs
(RS-232 pins). Targeted applications are PDAs, Palmtops,
and notebook and laptop computers where the low
operational, and even lower standby power consumption is
critical. Efficient on-chip charge pumps, coupled with manual
and enhanced automatic powerdown functions, reduce the
standby supply current to a 1A trickle. TSSOP packaging,
and the use of small, low value capacitors ensure board
space savings as well. Data rates greater than 250kbps are
guaranteed at worst case load conditions.
The ISL83387E features a V
L
pin that adjusts the logic pin
output levels and input thresholds to values compatible with
the V
CC
powering the external logic (e.g., a UART).
This device includes an
enhanced automatic powerdown
function which powers down the on-chip power-supply and
driver circuits. This occurs when all receiver and transmitter
inputs detect no signal transitions for a period of 30 seconds.
It power back up, automatically, whenever it senses a
transition on any transmitter or receiver input.
Table 1 summarizes the features of the ISL83387E, while
Application Note AN9863 summarizes the features of each
device comprising the 3V RS-232 family.
